Rails密码认证

Question

首先，我是rails的新手。所以请原谅我的新手错误。还在努力寻找可靠信息的最佳来源。很多东西都有点过时了。

我遵循Rails教程并使用密码身份验证。在我的应用程序中，我有用户和部门，它们之间有一个has_many through关系。这个关系称为manager_relationship。MY认证和用户授权工作。管理和取消管理按钮用于创建管理器关系。我还为每个部门设置了安全密码。我希望在创建经理关系之前要求用户输入部门密码。我在管理按钮旁边添加了一个密码字段。

模型:

department.rb
class Department < ActiveRecord::Base
attr_accessible :department_name, :password, :password_confirmation
has_many :manager_relationships, dependent: :destroy
has_many :users, through: :manager_relationships
has_secure_password

manager_relationship.rb

class ManagerRelationship < ActiveRecord::Base
attr_accessible :department_id
belongs_to :user
belongs_to :department
validates :user_id, presence: true
validates :department_id, presence: true
end

user.rb

class User < ActiveRecord::Base
attr_accessible :name, :email, :password, :password_confirmation
has_many :manager_relationships, dependent: :destroy
has_many :departments, through: :manager_relationships
has_secure_password

视图部门/show.html.erb

...
<div class="span8">
    <%= render 'manage_form' if signed_in? %>
</div>
</div>

departmnet/_manage.html.erb

<%= form_for(current_user.manager_relationships.build(department_id: @department.id), remote: true) do |f| %>
<div><%= f.hidden_field :bdepartment_id %></div>
<%= f.submit "Manage Department", class: "btn btn-large btn-primary" %>
<% end %>

控制器:ManagerRelationshipsController

class ManagerRelationshipsController < ApplicationController
before_filter :signed_in_user
def create
    @department = Department.find(params[:manager_relationship][:department_id])
    current_user.manage!(@department)
    respond_to do |format|
        format.html { redirect_to @department }
        format.js
    end
end

上面的代码可以工作。它成功地建立和破坏了一种经理关系。但是没有认证。任何用户都可以管理任何部门。我想要求管理用户输入一个部门密码来创建manager_relationship

这是我试过的。

departmnet/_manage.html.erb

 <%= form_for(current_user.manager_relationships.build(department_id: @department.id), 
remote: true) do |f| %>
##################This Was Added ##############
<div>
<%= f.label :password %>
<%= f.password_field :password %>
</div>
################################################
<div><%= f.hidden_field :department_id %></div>
<%= f.submit "Manage Department", class: "btn btn-large btn-primary" %>
<% end %>

ManagerRelationshipsController

class ManagerRelationshipsController < ApplicationController
before_filter :signed_in_user
def create
    @department = Department.find(params[:manager_relationship][:department_id])
            ########################The line below was Added ##########################
    if @department.authenticate(params[:manager_relationship][:password])
            ###########################################################################
        current_user.manage!(@department)
    respond_to do |format|
        format.html { redirect_to @department }
        format.js
    end
       ####################I added this##################
    else
        flash.now[:error] = 'Invalid password'
        render 'new'
    end
       ############################################################

Answer 1

理想情况下，因为用户是登录的，所以不需要密码，用户如何才能进入您的页面。也许你想要另一层保护来设置/取消数据，你可以使用

 @user = User.where(:email=>...).first 
 # Authenticating User sonce your email id is in session
 # You don't need to store password on manager_relationship
 # create attr_accessor 
 @user.authenticate(params[:manager_relationship][:password])
 # if user is authenticate then you can add/edit your data

Answer 2

我添加的代码是正确的。问题是我试图在无效密码后显示的flash消息。

if authenticate
else
flash.now[:error] = 'Invalid password'
render 'new'  <<I removed this line.>>
end

我的代码试图渲染manager_relationships/new，但它不存在。在我删除这个按钮后，按计划工作。但是闪光信息不会显示。我把它贴在另一个问题上，因为这是另一个话题。
